PAPER-CLIP.

Specification of Letters Patent.

ratentecl April 2, 1907.

Application filed August 20,1906. Serial No. 331,243.

To all whom, it may concern;

Be it known that I, CHARLES ROBERT MUELLER, a citizen of the United States, and a resident of Detroit, in the county of WVayne and State of Michigan, have invented a new and Improved Paper-Clip, of which the following is a specification.

My invention relates to an improved clip or binder for fastening sheets of paper or other material together; and its object is to provide a fastener that shall effectually secure together a comparatively large number of sheets.

My invention consists of a clip composed of a body portion and a tongue integral with each other, the body portion being in the form of a flat ring or loop and the tongue extending across the body portion and being curved in. a transverse plane.

In the drawings, Figures 1 and 2 are respectively plans of two forms of clips. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig. 4 is a crosssection on the line 4 4 of Fig. 2. Fig. 5 is a view of the clip of Fig. 3 en- J gaging a number of sheets of paper.

Similar reference characters refer to like parts throughout the several views. F

The tongues of paper-clips are usually made straight, and so when a clip is employed to secure any considerable number of sheets together an acute angle is formed between the tongue and the 'plane of the remainder of the fastener, causing the fastener to be efiective only at the apex of the angle.

In Figs. 1, 3, and 5, 1 is the loop of the clip, the spring-wire of which it is formed being extended across to form the tongue 2. Instead of being made straight the tongue is first curved outwardly, then inwardly, finally contacting with the loop diametrically opposite the place where the body and tongue unite and projecting a short distance beyond this point of contact, where it is again slightly depressed. The lower edge of the end of the tongue is slightly beveled to more easily admit the paper. IVhen the clip is placed over the edges of a number of sheets, as in Fig. 5, the outwardly-curved portion of the tongue will be entirely free from the paper, while the portion 3 of the tongue will press against the sheets, the grip of the clip thus being some distance from the edges of the sheets, and therefore effective, instead of merely at the very edge, where the effect is very slight. A further advantage of this construction is that when in use the part 3 has a tendency to force down a portion of the sheets into the ring, rendering the fastening more secure.

In Figs. 2 and 4: the body 4 has a straight portion 5, and the tongue 6 is given greater curvature at 7, thus adapting this form for large fasteners. Both. kinds may be made of any size and diameter of wire desired, and the curvature of the tongue will largely depend upon the work to be done.

Having now explained my improvements, what I claim as my invention, and desire to secure by Letters Patent, is

A clip or paper fastener constructed to form a ring, one end of the material deflected inwardly to cross the ring and form a tongue, said tongue being curved outward from the ring at the point of connection and curving back to a point within the ring and then ex tending to engage the opposite side of the rmg.

In testimony whereof I have signed my name in the presence of two subscribing witnesses.
